KVM cable that connects your computer.  
Built-In USB 2.0 Hub  
The SOHO KVM Switch features a built-in Hi-Speed USB 2.0 hub, so you can  
share two USB peripheral devices, such as a printer, with all your computers. There  
are two USB ports on the KVM Switch. One port is located on the back and the  
other is located on the front for easier access.  
Speaker/Microphone Support  
The SOHO KVM Switch allows you to share one set of speakers and one  
microphone with all your computers, so you won’t need to unplug and reconnect  
your speakers and microphone every time you switch access from one computer  
to the next.  
Direct-Access Port Selectors  
Direct-access port selectors, conveniently located on the front face of the SOHO  
KVM Switch, allow you to easily switch access from one computer to the next. You  
can change the KVM port or the audio/mic using these buttons.  
Cables  
All the required cables are 6 feet in length and are included in the box for easier  
installation. The cables are also smaller and easier to manage.  
LED Display  
There are two LEDs on each button. One indicates which port the KVM is on and  
the other indicates which port the audio/mic is on.

Installing the KVM Switch  
Pre-Configuration  
Where to Place the KVM Switch  
The compact size of the KVM Switch makes it perfect for desktop placement.  
Consider the following when deciding where to place the KVM Switch: whether  
or not you intend to use the direct-access port selectors; the length of the cables  
attached to your keyboard, mouse, and monitor; the location of your CPUs from  
your console; and the length of the cables you use to connect your computers to  
the KVM Switch.  
Cautions and Warnings  
Avoid having cables near fluorescent lights, air-conditioning equipment, or  
machines that create electrical noise (e.g., vacuum cleaners).  
Single-Switch Installation  
This section provides complete instructions for the hardware setup of a single KVM  
Switch. (F1DD102L or F1DD104L)

Installing the KVM Switch  
Powering Up the Systems  
The KVM Switch must be powered up before the computers.  
Once all cables have been connected, power up the CPUs that are attached  
to the KVM Switch. All computers can be powered on simultaneously. The  
KVM Switch emulates a mouse and keyboard on each port and allows your  
computer to boot normally. Your KVM Switch should now be ready for use.  
You can select which computer to operate by either the direct-access port  
selectors located on the front panel of the KVM Switch or through keyboard  
hot-key commands. Note that it will take 1–2 seconds for the video to display  
after switching. This is due to the refresh of the video signal. There is also  
re-synchronization of the mouse and keyboard signal that takes place. This is  
normal operation and ensures that proper synchronization is established.

Using the KVM Switch  
Selecting a Computer Using Direct-Access Port Selectors  
You can directly select which computer you wish to control by pressing the  
corresponding direct-access port selector next to the appropriate port. The LED  
will be lit to indicate that the port is currently selected.

Pushing the Audio LED on the right of the button allows you to independently  
switch your audio feed while continuing to work off of a different computer.  
Selecting a Computer Using Keyboard Hot-Key Commands  
A keyboard hot-key sequence consists of at least three specific keystrokes  
(hot-key sequence = [ScrLk] + [ScrLk] + Command key(s)).  
User-definable hot keys also allow you to customize your hot-key sequence.  
For example:  
SCROLL LOCK  
CAPS  
F12  
ESC  
NUM LOCK  
LEFT_CTRL  
RIGHT_CTRL

Hot-Key Preceding Sequence Configuration  
For users who want to use a preceding sequence other than two consecutive  
Scroll Locks, there is also one convenient way to configure it.  
1. Press “ScrLk” + “ScrLk” + H, and a beeping sound will signal readiness for  
a new preceding sequence selection [or press and hold down the center  
of the last front-panel button (Button 2 or Button 4) until you hear three  
beeps, then release the button].  
2. Select and press the key you would like to use as your preceding  
sequence (SCROLL LOCK, CAPS, F12, ESC, NUM LOCK, LEFT_CTRL,  
RIGHT_CTRL keys are available for selection), and you will hear a beep for  
selection confirmation. Now you can use the new preceding sequence to  
execute your hot-key commands.  
Note: Each keystroke within a hot-key sequence should be pressed within  
two seconds. Otherwise, the hot-key sequence will not be validated.

or  
You can use another method: Press and hold the last button to enter the hot-key  
setting mode.  
Step 1. Press and hold the last button (i.e., the second button on the 2-port model  
or the fourth button on the 4-port model) till you hear two beeps. Then  
release the button.  
Step 2. Within two seconds, you should hit any of the selectable hot-key triggers  
(y), y = SCROLL LOCK, CAPS, ESC, F12, NUM LOCK, LEFT CTRL, or  
RIGHT CTRL to be your hot-key trigger.

Notes:  
1. The USB keyboard hot keys allow faster and broader control of your KVM  
Switch and audio/mic switching in addition to the front-panel buttons.  
If you have configured a hot-key preceding sequence other than two  
consecutive scroll locks, you should change your hot-key sequence  
accordingly. (For hot-key preceding sequence configuration, please refer to  
the Quick Installation Guide.)  
2. When the binding of PC and audio and mic switching is enabled by the hot-key  
sequence: ScrLk + ScrLk + Q, any PC and audio and mic switching by hot keys  
are bound together. (However, the binding will not affect the independent  
front-panel button operation.) To remove this binding, use the hot-key  
sequence: ScrLk + ScrLk + W.

The audio/mic is independent to the KVM Switch and can be switched  
independently. This means that if you are working on port 1 of the KVM  
Switch, you can be listening to your music on port 3.  
You can switch the audio/mic in two ways:  
1.  
Using the direct-port selectors: The port selector has an Audio LED that  
indicates which port your audio/mic is on. Push the speaker icon on any of  
the four buttons and the audio/mic will switch to the corresponding port.  
2.  
Using the pre-defined hot key: Please see the Hot-Key Quick-Reference  
Table for a list of the hot keys.

Firmware-Upgrade Guide  
This firmware-upgradeable KVM Switch allows you to upgrade firmware contents  
whenever it is needed to enhance its compatibility to other devices or its  
functionality and performance. We offer both Windows and Mac versions of the  
upgrade utility. You can choose either one depending on the computer platform on  
which you are going to perform the KVM Switch firmware uploading. The correct  
firmware-upgrade procedures using the Windows and Mac upgrade utilities are  
described below. Please follow the instructions to complete your  
firmware upgrade.  
The firmware upgrade is performed through port 1 of the KVM Switch, so the KVM  
cables that are connected to port 1 should remain connected. Unplug all remaining  
KVM cables and peripheral cables connecting the KVM Switch to your computers  
or peripherals. You can leave the power cable connected to the KVM Switch. The  
keyboard, mouse, and monitor should be disconnected from the KVM Switch and  
plugged in directly to the host computer.  
The computer that is connected to port 1 of the KVM Switch will be performing the  
upgrade and will be referenced as the “Host PC” for this process.  
All but one of the cables connected to the KVM ports will be removed from the  
Switch. The cable connected to port 1 will remain connected. The USB connector  
at the other end of the port 1 cable will be plugged into a USB port on the host  
PC. The monitor connector will remain unplugged. The KVM console keyboard,  
mouse, and monitor are disconnected from the KVM Switch and then plugged in  
directly to the host PC.

Prepare your KVM Switch and the Host PC  
Note: The host PC must be running Windows 2000 or above in  
order to complete the firmware upgrade.  
Step 1.  
Ensure that the power adapter is connected to the KVM Switch. Check to make  
sure that the KVM cables for port 1 remain connected to the KVM Switch and the  
USB connector at the other end is plugged into a USB port on the host PC. The  
monitor connector is not used. The console monitor, mouse, and keyboard are  
disconnected from the console ports of the KVM Switch and plugged in directly to  
the host PC.  
Note: The power supply should also remain connected to the KVM Switch.  
Step 2.  
The cables that are connected to port 1 of the KVM Switch also need to be  
connected to the host PC. Connect the USB cable to the host PC.  
Important: Some host computers may not have enough USB ports to support  
the use of a USB keyboard, USB mouse, and the USB cable needed to  
perform the upgrade. (An example of this is a Mac mini, which only has two  
USB ports.) If this occurs, the keyboard does not have to be connected to the  
host PC since the mouse is used to perform the upgrade.  
Step 3.  
Power on the host PC and copy/download the firmware-upgrade utility,  
“Belkin Soho.exe”, and the firmware-upgrade file, “*.blk”, from belkin.com/support.  
17

Note: Before hitting the “Upgrade” button on the utility program, you should  
make sure that you are focused on port 1 of the KVM Switch where you  
have the computer connected. If not, switch to that computer before hitting  
the “Upgrade” button. Once the “Upgrade” button is pressed, the focus is  
immediately switched to the last button (port 2 on the 2-port model, port 4 on  
the 4-port model) and then back to port 1 after the completion of the upgrade.  
Step 8.  
After you click the “Upgrade” button, the file-transfer progress will begin in seconds  
and can be monitored through the advancement of the progress bar. Wait until the  
progress bar runs to its full length for the upgrade process to be completed.

What does flash-upgrade capability mean?  
You can update your KVM Switch firmware with flash upgrades, when needed,  
by going to belkin.com. This ensures that your KVM Switch works with the most  
current computers and devices.  
How does the KVM Switch allow the user to switch between ports?  
The KVM Switch supports two methods of port selection. You can select  
computers using specially designated keyboard hot keys, or independently  
access the desired port by pushing the direct-access port selectors.  
What is DDC?  
Short for Display Data Channel, DDC is a VESA standard for communication  
between a monitor and a video adapter. Using DDC, a monitor can inform a  
computer’s video card about its properties, such as maximum resolution and  
color depth, to ensure that the user is presented with valid options for configuring  
the display.  
What is the maximum video resolution that the KVM Switch supports?  
The advanced video circuit in the KVM Switch supports a maximum resolution of  
1920x1200 and analog resolution of 2048x1536. Such higher-resolution support  
is ideal for graphic artists and designers who depend on high-quality video.  
What are the benefits of the SOHO KVM Switch’s supporting audio and  
microphone inputs and outputs?  
The SOHO KVM Switch is perfect for the home- and small-office user who  
commonly uses multimedia applications. With multimedia support, you do not  
need an extra set of speakers for each computer that is connected to your KVM  
unit. The audio and mic also switch independently to the KVM Switch.  
Do I have to install any software to use the KVM Switch?  
No, the KVM Switch does not require any drivers or software to be installed  
in your computers. Simply connect all your computers to the computer/host  
ports on the KVM Switch, then attach one keyboard, monitor, and mouse to the  
“Console” port and it is ready for use.

cable is connected and inserted properly between the computer  
and KVM Switch for the appropriate port.  
• If you are using the KVM Switch for video switching only and have  
no keyboard and mouse connection between the KVM Switch and  
PC, you will need to purchase the optional 9V DC, 600mA power  
adapter (F1D065-PWR for your appropriate country).

Troubleshooting  
KEYBOARD  
Problem:  
Computer does not detect keyboard and I get a keyboard error  
reported at boot up.  
Solution:  
• Check that the keyboard cable between the KVM Switch and the  
computer is connected properly. Tighten any loose connections.  
Try swapping your keyboard with a different one.  
Try connecting the computer to a different port.  
• If you are using the keyboard software that was included with  
your keyboard, uninstall it and install the standard Microsoft  
keyboard driver.

• Check the cables and make sure that they are inserted properly.  
Problem:  
The computer boots up fine, but the mouse does not work.  
Solution:  
• Make sure it is plugged in properly.  
• Make sure the mouse works when directly plugged into the  
computer. Rebooting may be necessary when trying this.  
Try a different mouse.  
Problem:  
When I switch from one port to another, mouse movement is completely erratic.  
Solution:  
• Make sure you do not have more than one mouse driver installed.  
• Make sure that the driver is either for a standard USB mouse or a  
PS/2 or USB mouse compatible with Microsoft.  
• Avoid moving the mouse or pressing the mouse button when  
switching ports on the KVM Switch.  
You can reset the mouse and resume proper mouse movement  
simply by unplugging the mouse from the front of the KVM Switch  
or about 2–3 seconds, and then plugging it in again.  
GENERAL  
Problem:  
My computer does not boot when connected to the KVM Switch and works  
fine when I connect the keyboard, video, and mouse directly to it.  
Solution:  
• Make sure that the keyboard and mouse cables are connected  
tightly between the KVM Switch and the computer.  
• Check that the keyboard and mouse cables are not crossed.

Troubleshooting  
Problem:  
I am connecting my computer to the SOHO KVM Switch via USB and my  
keyboard and mouse do not work.  
Solution:  
• Prior to connecting the SOHO KVM Switch, make sure that the HID  
USB driver is installed on each computer. (To install the HID USB driver,  
connect a USB mouse and USB keyboard to the computer. Windows should  
automatically install the drivers.)  
Problem:  
Some of the keys on my keyboard are not functioning properly when I use a  
Mac computer.  
Solution:  
• Because you are using a PC keyboard on a Mac computer, a few of the  
option keys on your PC keyboard may be reversed. All major keys will  
function as labeled.

Problem:  
The progress bar stops for a long time without any advancement.  
Solution:  
Press and hold down the first front-panel button until two beeps are heard, and  
click the upgrade button on the upgrade utility program. The firmware-upload  
process will begin immediately, and you will see the progress bar advance  
gradually to full length. However, if the progress bar just stops somewhere in the  
middle and goes no further for a long time (longer than five minutes), there might  
be some problem.  
If so, simply unplug all the cables from the KVM Switch and start the whole  
firmware-upgrade procedure again as described in the Firmware-Upgrade Guide.  
However, if you find that the mouse and keyboard no longer work from the  
console of your KVM Switch, you can connect them directly to the host computer  
(although the USB cable still has to be reconnected to the KVM Switch), and  
complete the rest of the firmware-upgrade procedure.  
Note: Make sure that you have closed any unnecessary running programs on  
the host computer, such as antivirus, system-monitoring, or automatic updates,  
before you perform the upgrade procedure.  
Note: This firmware is crash-proof. If the upgrade has failed before its  
completion, just repeat the procedure again for another try.  
Problem:  
In the middle of the firmware-file transfer, my computer was shut down  
by an unexpected power failure or the USB connection was broken. What  
should I do now to restart the whole firmware-upgrade procedure?  
Solution:  
Follow the instructions as described in the previous question.
